[0002] At present, the processing procedures of automobile bracket fender parts are mainly stamping, welding and riveting. The stamping process is used to process cold-punched single-piece semi-finished products, the welding process is used to complete the welding of the bracket fender welding surface, and the riveting process is used to complete the riveting of the two nuts of the bracket fender for connection and installation. The traditional riveting process is hand-held riveting, which is done by holding the parts and contacting the nuts with the riveting holes of the parts to complete the riveting process. Since the bracket fender riveting is manually hand-held riveting, when riveting the bracket fender parts, the operator needs to pull the height of the two nuts to within 10mm, and the riveted parts are prone to missing rivets, which affects the assembly work of the client in the later stage.
